_D_e_s_c_r_i_p_t_i_o_n:

     These functions are intended to replace some commonly used base R
     graphics functions in panel functions.

_U_s_a_g_e:

     larrows(x0, y0, x1, y1, proportion, ...)
     llines(x, y, ...)
     lplot.xy(xy, ...)
     lpoints(x, ...)
     lsegments(x0, y0, x1, y1, ...)
     lsegments(x1, y1, x2, y2, ...)
     ltext(x, ...)
     panel.arrows(...)
     panel.lines(...)
     panel.points(...)
     panel.segments(...)
     panel.text(...)

_A_r_g_u_m_e_n_t_s:

 x, y, x0, y0, x1, y1, x2, y2, xy: locations. x2, y2 present for S
          compatibility 

proportion: The proportion of the arrow edges compared to the whole
          line. This is different from 'arrows'

     ...: other arguments, including ones to control graphical
          parameters like color, line type, etc. For devices that
          support alpha-transparency, a numeric argument 'alpha'
          between 0 and 1 can be supplied. Be careful with this, since
          for devices that do not support alpha-transparency, nothing
          will be drawn at all if this is set to anything other than 0. 

_D_e_t_a_i_l_s:

     These functions are meant to be grid replacements of the
     corresponding base R graphics functions, to allow existing Trellis
     code to be used with minimal modification.  The functions
     'panel.*' are essentally identical to the 'l*' versions, are
     recommended for use in new code (as opposed to ported code) as
     they have more readable names.

     See the documentation of the base functions for usage. Not all
     arguments are always supported. All these correspond to the
     default methods only. For 'ltext', only values 0, .5 and 1 for
     'adj' have any effect.

_N_o_t_e:

     There's a new 'type="H"' option wherever appropriate, which is
     similar to 'type="h"', but with horizontal lines.

_S_e_e _A_l_s_o:

     'points', 'lines', 'text', 'segments', 'Lattice'
